Expression of salt-tolerant genes regulated by a bZIP gene in Tamarix hispida willd

The genes whose expression regulated by a basic leucine zipper (bZIP) gene from Tamarix hispida were investigated in the present study. Expression of stress-tolerant genes including SOD, POD, ATPase, GST, LTP and LEA were compared between bZIP transformed and non-transgenic plants under normal growth and salt stress condition. The results showed that under normal condition, poxN1, TOBPXD, TOBLTP and ltp1 genes may be directly regulated by bZIP, while the others may be not regulated by bZIP directly. Under salt stress bZIP regulated the expression of some stress resistance genes and enhance their expression level.
